There will soon be a new use, about 75 miles south of Erie, for the state’s growing supply of natural gas.

A New Jersey company plans to spend $750 million to build a natural gas-fired power plant in Lawrence County, according to a report in the Pittsburgh Tribune-Review.

County officials told the newspaper that LS Power plans to build on a former explosives manufacturing site that has been abandoned for more than 40 years.

The company, which has not sought tax breaks, expects to employ as many as 500 workers during two years of construction and then pay about $500,000 annually in local school taxes, company and county officials said.

“It’ll be tremendous. It is a big deal,” County Commissioner Steve Craig told the newspaper. “In terms of the footprint in its community, you’ll barely see it, you won’t hear it. Its emissions will be relatively low because it’s burning natural gas. … So the impact isn’t all that great. (But), the fiscal impacts will be really nice.”
